I have a 629 Classic with a 6 1/2" full under lug barrel and the factory Hogue grips.
I also have a Model 29 with a 4" barrel and the factory target stocks.
When shooting the same ammo in a side by side comparison both my son and I felt that the target stocks felt better even though the 29 is noticeably lighter.
I think that it is due to the fact that the stock targets are much wider than the Hogues and spread out the felt recoil better.
